Your furnace works hard every winter to keep your home warm and safe. But like any piece of equipment, it can develop problems over time. Catching these issues early can save you from costly repairs or even a full system replacement later on. Absolute P&M Services will share some of the most common signs your furnace may be in trouble and when you should call a professional for help.

Unusual Furnace Noises

It is normal for a furnace to make a low hum or whoosh while running. But if you hear banging, clanking, squealing, or rattling, it could mean:
• Loose components
• Worn belts or bearings
• Blower motor issues
• Problems with the ignition or burners
Unusual noises rarely go away on their own. Have them checked immediately to prevent further damage.

Uneven or Weak Heating

If some rooms are warm while others stay cold or the air coming from your vents feels weak your furnace may be struggling. This could be due to:
• A failing blower motor
• Dirty or leaky ductwork
• Clogged filters restricting airflow
Replace filters regularly and schedule a professional inspection to restore even heating.

Short Cycling Furnace

Does your furnace turn on and off more frequently than usual? This “short cycling” can be due to:
• Dirty air filters
• Malfunctioning thermostat
• Overheating due to worn parts
Short cycling wastes energy and puts extra stress on your system. Have a technician find and fix the underlying cause.

Increasing Energy Bills

If your energy bills are climbing but your heating habits have not changed, your furnace may be losing efficiency. This could mean dirty components, worn parts, or a system nearing the end of its lifespan. A tune-up can often restore efficiency but if your furnace is old, replacement may be more cost-effective.

Constant Heating Repairs

If you are calling for service multiple times a season, your furnace is sending a clear signal it’s in trouble. Frequent repairs add up quickly and may indicate it’s time to invest in a new system.

Lingering Furnace Odors

While a faint burning smell at the start of heating season can be normal, persistent or unusual odors can be a sign of:
• Gas leaks, a rotten egg smell.
• Electrical issues, a burning or metallic smell.
• Mold or mildew in the ducts, a musty smell.
If you ever suspect a gas leak, evacuate your home immediately and call emergency services.

The Furnace is Old

Even with excellent maintenance, most furnaces last about 15–20 years. If yours is approaching that age and showing any of the above signs, it may be time to consider replacement rather than more repairs.

Protect Your Home With Regular Maintenance

The best way to avoid furnace troubles is annual professional maintenance. A tune-up includes:
• Cleaning burners and filters
• Inspecting heat exchangers and safety controls
• Checking electrical and gas connections
• Ensuring proper airflow
